HOLMDEL, N.J., Oct. 23 /PRNewswire-FirstCall/ -- Vonage, a leading provider of
digital phone services, announced today that it was recently granted approval
by the U.S. Patent and Trademark Office for an internally developed patent,
called "Method and Apparatus for Enhanced Internet Telephony." The invention,
which was filed for patent in 2003, makes it less likely for customers to
encounter dropped calls, incomplete attempted calls or other communication
problems resulting from typical router function and behavior.

"This is an exciting moment for Vonage as we continue to expand our patent
portfolio to help create a more reliable calling experience for our
customers," said Louis Mamakos, Chief Technology Officer and Executive Vice
President. "This patent further reflects the depth of talent and creativity
we have here at Vonage."

The patent -- No. 7,417,981 -- pertains to improvements in Internet telephony
where Network Address Translation (NAT) is required. The patent addresses the
issue of a router losing an outbound port during an Internet telephone
connection. To avoid the router timing out and closing the outbound port, the
patent causes the media terminal adapter to send an outbound message to the
Internet telephony regional data center.
